PLAYING-BALL.

SPECIFICATION forming part of Letters Patent No. 714,918, dated December2, 1902.

Application filed August 19, 1902. Serial No. 120,194. (No model.)

To @ZZ whom if may concern:

Be it known that I, ELEAZER KEMPSHALL, manufacturer, a citizen of theUnited States, residing at No. 41 High street, in the city of Boston,county of Suffolk, and State of Massachusetts, have invented certain newand useful Improvements in Playing-Balls, of which the following is aspecification.

My invention relates to improvements in playing-balls, and has for itsobject to provide a ball which shall have its weight accuratelycentered, thereby rendering said ball truer in its flight thanplaying-balls as heretofore constructed.

According to my present invention I construct a playing-ball by Windingor coiling some highly-elastic subst-ance, preferably in the form oftape, ribbon, strips, or threads, under very high tension around a coreor center piece composed, preferably, of celluloid or gutta-percha. Thewinding or coiling of the said elastic substance proceeds until itreaches the required diameter of the inner part or filling of the ball.Between the various coils or windings I interpose a resilient substance,such as celluloid or guttapercha, preferably in the form of cups orhemispheres. I may employ a series of such cups of different diametersand inclose the respective windings therein. When the said inner part orfilling has attained a sufficient diameter, it is placed in cups orhemispheres of a plastic material and subjected to a high pressure, asalready described in the specifications of some of my said formerapplications.

In order that my said invention may be clearly understood and readilycarried into effect, I will now describe the same more fully withreference to the accompanying drawings, in which- Figure 1 is a view,partly in section, of a playing-ball constructed in accordance with myinvention. Fig. 2 shows a viewof the inner part or filling prior to itsbeing placed within the plastic orouter shell. Figs. 3 and 4 show saidinner part or filling with the elastic material wound or coiled todifferent diameters and inclosed within the cups.

Referring to the drawings, CLX is the core or 5o center piece, formed,preferably, of celluloid.

c is the elastic materiale-for instance, rubber in the form of strips,tape, or bandswhich is wound or coiled around the center piece a' untilit reaches approximately the diameter shown in Fig. 3, when it isinclosed within a very thin but resilient substance, such as Celluloidor gutta-percha, in the form of cupsor hemispheres a2. Outside of thissubstance the winding of the inner part or core is resumed, and if it isdesired to interpose more than one covering of celluloid or othermaterial the inner part or filling may be inclosed in another pair ofcups as, preferably when said inner part or filling has reached thediameter shown in Fig. 4. The winding of the elastic material can thenbe resumed outside the cups or hemispheres a3, and when the diameter ofthe inner part or filling has attained approximately the size shown inFig. 2 it is inclosed in the outer shell A, of plastic material, such ascelluloid or gutta-percha, as showny in Fig. l. The whole is thensubjected to pressure and finished offin the usual manner.

Vhen the balls have been removed from the molds, they only require tobe,painted, after which they are ready for use.

It is obvious that, if desired, I may interpose the gutta-percha orother material at only one part of the coil or winding, in which casethe winding of the elastic material over the gutta-percha at c2 would becontinued until the inner part or core-filling attains the diametershown in Fig.. 2. lt will of course be readily understood that thegutta-percha or other cups may be interposed between the elasticwindings at any preferred diameter. It will be found that by interposingthe gutta percha or other cups at one or more places between the rubberwindings, as above described, the center piece will be more certainlyretained in the center of the ball and the weight therefore more evenlydistributed than 4when they are absent.

What l claim, and desire to secure by Letters Patent of the UnitedStates, is-

1. A playing-ball comprising in combination a center piece, a pluralityof concentric windings thereon of elastic material under tension, and asti springy shell interposed between said windings, substantially asdescribed.

2. A playing-ball comprising in combination a center piece, a pluralityof concentric ICG windings thereon of elastic material under severetension, a spherical shell comprising cups interposed between saidwindings, and anouter shell inclosing the whole, substantially asdescribed.

3. In a playing-ball the combination of an external shell formed inportions and welded together, a hard center piece, a plurality ofwindings between said external shell and center piece, and a shell ofhard resilient material between each winding and the next, substantiallyas described.

4. A playingball comprising in combination a center piece, a pluralityof concentric windings thereon of rubber tape under tension, and a shellinterposed between said windings, substantially as described.

5. A playing-ball comprising a core, tense windings of rubber thereon, athin hard shell upon said windings, a softer layer of resilient materialupon said shell, and a hard cover.

6. A playing-ball comprising a core, tense windings of rubber thereon, athin hard shell upon said windings, a softer layer of resilient materialupon said shell, and a hard cover holding said resilient material undercompression.
